DESCRIPTION

The UTC US205 is a cost-effective, low-voltage, low switch-on resistance (typ. 100mΩ) high-side Power Switch IC. It has a 20μA low quiescent supply current that meets the requirements of battery-powered portable equipment.

The UTC US205 incorporates protection circuits, such as an over-current protection circuit, a short fold back circuit, a thermal shutdown circuit and an under-voltage lockout circuit for overall protection. Besides, a slew rate controlled function is embedded for turn-on rising time control.

The UTC US205 can be usedin applications, such as Cellular Phones, Digital still Camera, Hot swap Supplies, Notebook Computers, Personal Communication Devices, Personal Digital Assistants and so on.

The UTC US205 is available in SOP-8 package.
